Table - best surf conditions forecast for Jaconé over the next 16 days.
Alright, Rusty here, let’s break down what’s in the water at Jaconé.
We’re starting out with a solid little run of surf kicking off Friday morning. Nothing huge, but a consistent 3 to 4 foot SE swell moving through the weekend. The water is about average for July, so no surprises there. The real standout is Saturday morning, July 11th. The swell pushes to 4 feet out of the SE, with a 13-second period, and the wind goes dead calm – glassy. That’s going to be butter-smooth, with moderate wave energy (514). It’s a consistent spot, so you’ll get waves, but expect some company.
Sunday the 12th gets ugly. The wind goes strong cross-onshore from the WSW at 28 mph, and the swell drops to 3 feet. With that much wind, this beach-and-reef setup is looking more fun for the kiteboarders than paddle surfers.
Monday the 13th and Tuesday the 14th bring a bigger pulse of 6 to 6 foot swell from the S and SSW, but the wind is onshore or cross-onshore, so it’s messy. The energy is solid (905 and 614), but the surf quality is poor.
We get a clean window again on Wednesday morning, the 15th. Light offshore NE wind with 3 feet from the SSE (322 energy). Nice and clean. Then Thursday morning, the 16th of July, is the next highlight: 5 feet of ESE swell, 8-second period, light offshore NE breeze. That’s 510 energy and clean lines. Mark that one.
The second week is more of a pick-and-choose. From Friday the 17th through Monday the 20th, the mornings are clean with 3 to 6 foot swells from the ENE, but the periods are short (7-8 seconds), so it’s more windswell. The 20th of July, Monday morning, is the best of that bunch: 6 feet from the ENE, light offshore NNE wind, and clean (462 energy). That’s a little punchy for beginners.
After that, there’s a few days of mixed winds and onshore slop, then a glassy morning on the 23rd of July. That’s a Thursday, over a week away, so don’t bet the farm, but 5 feet from the ENE with glassy conditions is a tasty prospect. The last few days into the 25th of July show a shift to a longer-period S swell, but it’s far out and the energy is lower.
Bottom line: your best bet is Saturday morning, July 11th – glassy, 4 foot SE swell. Thursday morning, July 16th is your second call. The rest is a mix of fun mornings and a few days to take off.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
